HFS Hammer Feed Scaler:

Breaker Technology’s HFS (Hammer Feed Scaler) Series of Scalers are engineered and manufactured to handle key requirements of the scaling operation:

When testing seams or rock laminations, the tool will occasionally get wedged in the material. Withstanding the resulting prying loads requires a relatively large size breaker with a large diameter tool and heavier body. The BX8 provides a blow energy of 800 ft lbs and can be adjusted to suit the ground conditions to avoid problems from over-scaling. The hydraulic system is a two-circuit design; one complete system for the carrier and one for the breaker operation, making it quick and easy to identify and address maintenance issues and keep downtime to a minimum.

Shock loading to a boom system is common when a large rock falls unexpectedly onto the boom arm during the scaling process. The HFS Series Underground Scaler is ruggedly built to handle 1.5 T and abnormal loads during scaling. A heavy-duty telescopic boom knuckle comfortably withstands loads. The carrier is further enhanced with four hydraulically operated stabilizers which remove any stresses on the axles during scaling. For any carrier with a boom, stability and good weight distribution play a vital role in reducing shock loads, ultimately providing longer life and reduced maintenance.

All cylinders and the hydraulics are protected to avoid damage from the loose material. All cylinders and hoses are positioned under the boom or housed to protect from falling rock. A protective canopy or cabin ensures safety while operating from the operator’s seat. A remote control pendant for the boom and breaker is also available.

Features & Benefits:

Similar to precise manual scaling, operators use sight and sound to evaluate scaling requirements. HFS Series Scalers are designed for mine ready application
